Hi,Tom Likens wrote:If you still have it please send me as much of the game information as you can find for the Djinn forfeiture, (I'm assuming this was a loss on time). Djinn may not be the strongest engine in existence, but I do like it to be stable and as bug-free as possible, so I take these bug reports seriously.
Also, if you wouldn't mind please send me the name of the exact Djinn executable you used as well as the particulars of the computer you ran it on, (i.e. memory, any configuration files, was ponder on or off, the name of the GUI you ran the tournament under etc., basically, anything that you think would help).
thanks,

I'm afraid I don't have much info beyond my setup and the PGN - I have logging turned off.
Games are played under Arena 3, with a 6+4 time control, ponder off - because of the increments, all time losses I've seen has been because an engine stops responding - and it seems so here too, as Djinn had a forced mate on the board, and had moved instantly the previous few moves. Looking at the game, I wonder if the problem might be TB related, as the position had just been reduced from 5 to 4 pieces when Djinn stopped moving (I have all TBs up through 5 men installed on harddrive.)
The exact Djinn file was djinn992_x64_popcnt.exe . My computer is a 6-core i-970, running Windows 7 professional, and with 6 GB RAM.
